LOOM-SHUTTLE.

and State of Massachusetts, have invented.

a certain new and useful Improvement in Loom-Shuttles, of which thefollowing is a specification.

The present invention consists in an improvement in connection with theweft-carrier holding-spring of shuttles used in automaticweft-replenishing looms wherein the replenishment of weft is effected bydischarging the spent weft-carrier from the shuttle and substituting afresh one therefor.

This application is a division of'application filed December 3, 1909,Serial No. 531,172.

" The improvement is illustrated in the accompanying drawings, wherein:

Figure 1, is a plan view of one end of a shuttle equipped with theimprovement. Fig. 2, is a vertical section in the plane indicated by theline 22 in Fig. I. Fig. 3, is a cross-section in the plane indicated bythe line 33 in Fig. 2. Fig. 4:, is a perspective view of theweft;carrier guide, a portion being broken away.

A, is the body. of the shuttle which at one end is furnished with ashuttle spring, having two separated elastic jaws, B, B, Which serve tograsp and yieldingly hold the buttend of a weft-carrier, as is common inloom shuttles for automatic weft-replenishing looms. The illustratedshuttle spring with its two jaws and its intervening shank is made of asingle piece of sheet steel, bent into shape, as set forth inapplication for Letters Patent of the United States filed by me October15, 1909, Serial No. 522,814. As in that application, the single pieceshuttle spring has its double wall shank located and fitting Within arecess of the shut-' tle chamber and is secured to the shuttle by meansof a bolt C, extending through holes in the two separated walls D, D, ofthe shank, as shown in Fig. 3. This bolt at its screw-threaded endengages a retaining nut E, all as usual.

On account of the yielding character of the shuttle body alongside 'therecess in which the shuttle spring shank fits, the pres sure, employedin tightening the bolt C, in its nut E, frequently causes the shuttlewalls to approach each other, thereby forcing the Specification ofLettersi 'atent.

this application filed June 24,

two walls of the shuttle spring shank slightly toward each other, withthe result thatthe free ends or jaws 15, B, of the shuttle spring may bebrought so close to each other that the space between them is notsufficiently adequate to readily receive the butt of an incomingweft-carrier. This may result in occasional breakage 01', at least, infailure to properly receive the incoming weft-carriers in everyinstance. 7

The present improvement consists in the means employed for preventingany collapsing or yielding of the walls of the shuttle spring shank dueto the pressure of the retaining bolt C. In connection with the shuttlespring there is employed the usual directing guide F, for directing thebutt of an incoming weft-carrier into proper position between the jawsof the shuttle spring, and it is shown, as in the aforesaid application,with an upper arm G, having a hole a, for the reception of the screw H,which holds the guide in place in the shuttle. This to arm G, of theweft-carrier guide is formed with a down bent spacing tongue I, which ismade by partially cutting or stamping a hole Z), in the said arm (seeFig. 4t) and bending down the spacing tongue. This spacing tongue isjust wide enough to enter between the two walls, D, D, of the shank ofthe shuttle spring and to closely lit the space between said walls, asshown in Fig. 3. Accordingly, this spacing tongue extending into andfitting the space between the walls of the shuttle spring, shank,prevents any forcing of said walls toward each other as the result ofthe compressive action of the holding bolt C.

I claim-- 1. A loom shuttle having, in combination, a weft-carrierholding spring composed of a single piece of steel bent into shape witha double wall shank for connection withihe shuttle; a retaining boltpassing through the body of the shuttle and through holes in the twowalls of the said shank: and a welt carrier guide ha ring a securing loparm crtending above the shuttle spring: shank, said top arm having anintegral down turned tongue extcndin; into and filling the space betweenthe two walls of lhc shuttle spring shank.

2. A loom shuttle having. in combination, a weft-carrier holding s,fu'inw ilh a double tongue extending into and fitting the space between thetwo walls of the shuttle spring shank.

3. A loom shuttle having, in combination, a Weft-carrier holding springvwith a double Wall shank for connection withthe shuttle;

a retaining bolt passing through the body of the shu tle and: throughhoie in the two Walls 0 the said shank; and a weft-carrier guide havinga tongue extending into and fitting the space between the two Walls ofthe shuttle spring shank.
